Damn right that SP2 has made more obvious changes than SP1 did... and I hate most of them.
1) It installs DirectX 9.0c which isn't compatible with some games
2) It literally forces you to restart your computer just after installing updates (if you choose not to, it will bug you about it every 10 minutes or so)
3) Internet Explorer has become a pain to use with the new built-in popup blocker... the Google bar is much better at this. M$'s new blocker can't even distinguish between 'good' and 'bad' popups. Thank God you can disable it...
4) The new security center is a pain, something that you'll choose to disable instantly after installing the SP. Here's why I hate it: I'm running Norton Internet Security 2003 with everything completely updated (this includes both firewall and antivirus), and the M$ security center was unable to detect this! It kept on saying "Your firewall & antivirus status is unknown.. bla bla". Sometimes it even managed to detect Norton and it was satisfied, but mostly it didn't.
5) Even downloads via Internet Explorer have become a pain... you have to first click the bar "A download was blocked. Click here to download the file" before you're permitted to get the file.
I could probably go on, but...
What do you guys think about it anyway?
